Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Wwbn/avideo, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In AVideo, a normal user can make a Meeting Schedule where the user can invite another user in that Meeting, but I found out that it did not properly sanitize the malicious characters when creating a Meeting Room. This leads the attacker to put malicious scripts. Impact: Since any USER including the ADMIN can see the meeting room that was created by the attacker this can lead to cookie hijacking and takeover of any accounts without user interaction. Step to Reproduce: 1. As normal USER go to Meet -> Schedule https://demo.avideo.com/plugin/Meet/ 2. In "Meet topic" field put XSS payload Example: "><img src=x onerror=alert('Pawned+by+Gonz')> 3. Then click Save 4. Now as ADMIN go to Meet -> Schedule -> Upcoming https://demo.avideo.com/plugin/Meet/ 5. Then the XSS payload that normal USER created will be executed Video POC: https://youtu.be/Nke0Bmv5F-o
